Problems solved by technology
However, the current electronic devices (such as mobile phones) also have great restrictions on the volume of the camera module, and the occupied volume of the motor increases correspondingly with the increase of the lens.
In other words, with the trend of lenses becoming larger and heavier, it is difficult for the driving force provided by the motor to increase accordingly
Under the premise that the driving force is limited, the heavier the lens, the shorter the motor can drive the lens to move, which affects the anti-shake ability
On the other hand, the heavier the lens, the slower the motor can drive the lens to move, and the longer it takes for the lens to reach the predetermined compensation position, which will also affect the anti-shake effect

The present application relates to a driving structure for an optical actuator, comprising: a first driving part adapted to mount a lens, a lens driving coil being mounted on a first movable part of the first driving part; the second driving part is suitable for installing the photosensitive assembly, the photosensitive assembly driving coil is installed on a second movable part of the second driving part, the second movable part is located below the second base part, and the photosensitive assembly is located below the second movable part; wherein the first driving part and the second driving part are provided with a common magnet which is arranged on the first base part or the second base part, and the first driving part drives the lens to translate in the x-axis direction and the y-axis direction through electromagnetic induction of the lens driving coil and the common magnet. The second driving part drives the photosensitive chip to translate in the x-axis direction and the y-axis direction through electromagnetic induction of a photosensitive component driving coil and a common magnet; and the first driving part is mounted on the upper surface of the second base part. The invention also provides a corresponding camera module.
Description
[0001] Related applications [0002] This application is a divisional application of the parent case entitled "Drive Structure for Optical Actuator and Corresponding Camera Module" and filed on November 25, 2020 with the Chinese Patent Application No. 202011338741.2. technical field [0003] The present invention relates to the technical field of camera equipment, in particular, the present invention relates to a driving structure for an optical actuator and a corresponding camera module. Background technique [0004] With the increasing demand of consumers for mobile phone photography, the functions of mobile phone cameras (ie camera modules) are becoming more and more abundant, and functions such as portrait shooting, telephoto shooting, optical zoom, and optical image stabilization are integrated into the limited-volume camera. , and autofocus, optical image stabilization, optical zoom and other functions often need to rely on optical actuators (sometimes also called moto...
